1. A method for estimating an analyte value from a continuous analyte sensor, the method comprising:

  • receiving a data stream from the continuous analyte sensor for a first time period;

    estimating at least one analyte value for a second time period based at least in part on the data stream for the first time period; and

    determining, using electronic circuitry, a variation of the at least one estimated analyte value based at least in part on a clinical risk analysis of the at least one estimated analyte value, wherein the variation comprises boundaries that represent a range of possible variations of the at least one estimated analyte value for the second time period.
